Many gun launched projectiles spin to maintain in-flight dynamic stability. This spinning often induces the gyroscopic phenomenon known as precession, or coning. Coning poses a problem for actively controlling the projectile. A control scheme is proposed that can compensate for the coning angle of the projectile and allow front-mounted canards to efficiently change the projectile flight path without reaching a stall condition. Closed-loop regulation and H2 control theories are employed to construct the controller.
